Answer:
First question: t = 22
Second question: j + 10
Step-by-step explanation:
First question: The last step tells us that there are a total of 22 people in the lunchroom. If t = total amount of people in the lunchroom than t would equal 22 according to the last step.
Second question: According to the third step, 10 students join the remaining students who are still in the lunch room. If j = students in the lunch before the 10 students join, then the expression or equation that represents the 10 students that join the lunchroom would be j + 10 because 10 students joined the students that were in the lunchroom before them.
